  • Getting “fat adapted” has very little to do with your diet; rather, it is about training the body to feed itself from fat stores during activity. A proper diet is a whole food, plant-based diet — no processed foods, no oils.

  • Brad,

    I listened to your interview on Trail Runner Nation and I’m excited to read your book.

    I’m currently a vegan soldier, crossfitter, and ultrarunner. I go back and forth on the fat versus carbs things. I love reading Dr. Esselstyn, Dr. McDougall, and Dr. Campbell’s works and they are all greatly against fat.

    Right now I’m reading The Atkins Diet book, just cause I like to study different things. I always wonder what the differences are of a Whole 30, Paleo, or your Primal diet compared to the Atkins Diet?

    One other question I have is what do you say to the Crossfit folks that do HIIT all the time but still do the Paleo diet? And then their is the Crossfit Endurance crowd that says yes to the paleo diet but throw out all the MAF runs and only do 3 hard runs a week? Just liked to see your thoughts on the subject.

    Thanks again for the great listen. It got me through a solid 6x1200m Interval run.


  • I have a question:
    We have two theories shared with us here on Trail Runner Nation.
    This one about low carb, fat adaptation.
    Then we have the theory of Brian MacKenzie, founder of crossfit endurance, ultrarunner and co-author of “Unbreakable Runner, Unleash the Power of strength and conditioning. (December 6, 2014)

    These two are at polar opposites with both having great points.

    I’m thinking to do this right, use the heart rate and fat adaptation method till at race weight and meeting goals, then switch to the other which is more intense training but less time, less mileage.

    What say you all?
